I've recently started using this great herb Salvia. I started with 5x - a couple of pinches (don't have a scale), ONE large bong hit really did the trick for 10 minutes. Reality peeled away like an onion and I saw "the others". It was like I was on another plane of existence.
Words of advice:
Have a sober "sitter" with you the first few times. Some folks have gotten up. Someone needs to be there to make sure you don't fall and get hurt or walk outside.
Relax in your favorite chair in a QUIET environment.
turn the lights really low
Turn on some killer tunes - they need to be moody...staty away from Slayer, etc...lol. Classical enhances the experience immensly....Holst, or Wagner are my favorite to listen to when I use Salvia.
Start with a little and work your way up to a bigger dose.
Keep the flame on the herb as you are hitting it. Salvanorum-A (the active composition) needs high heat to fully vaporize.
Hold the hit in for 30 seconds.
BTW, it doesn't taste that bad...it is a little harsh, but for experienced smokers should NOT make you cough.
PM me if you need some good places to either buy extract (5x, 10x, etc), live plants, or straight dry leaf. I've gotlinks to a few good online vendors that won't rape yer wallet.
Salvia is great, and not meant to be a party drug.
